video I made at strawberry

[2knots]

Mine only has one zinc that has a ground wire running to it from the motor the other are just bolted to the motor or hull, clean the zincs Not the connections, I use a Drexel with a stainless wire wheel and clean them right on the boat

How often do you need to clean the zincs?

I clean mine 1 time every year ( spring when I do the maintenance) with the boat only in freshwater, when I was fishing the salt I’d do it twice
